Private Uniswap desk · Powered by Zama FHE
Trade Uniswap without showing your size.
Encrypted balances and swap intents on the Zama Protocol, settled against Uniswap liquidity. Protocol fee 0.05%. Live pilot on Ethereum Sepolia.
Mempool privacy isn't balance privacy.
Private RPCs hide a transaction for a moment. They don't hide your wallet balance or your trade history. Large clips still paint a target for copy-traders and wallet-clustering tools. Noctis moves the sensitive part, your book and your intent, into encrypted state before the trade ever reaches the pool.
Private intent. Public liquidity.
Deposit
Move ETH or USDT into the vault. Your balance is stored as an encrypted value that only you can decrypt.
Sign an intent
Your swap amount is encrypted client-side and signed. Nobody watching the chain can read your order.
Settle on Uniswap
After a decryption proof, the Noctis contract swaps against Uniswap as a proxy. The pool never sees your wallet.
Withdraw
Pull your funds whenever you want. Output from swaps is credited back to your encrypted balance.
What stays private, honestly.
We pair every privacy claim with its limit. Noctis is a privacy layer, not a mixer, and we say exactly where the boundary sits.
Encrypted
- Vault balances, stored as FHE ciphertexts
- Pre-trade swap intents and amounts
- Your identity toward the pool: Uniswap sees the Noctis contract, not your wallet
Clear at settlement
- The fill size when Uniswap executes (AMMs need numbers)
- Deposit and withdrawal transactions, attributable to your address
- The Noctis contract as the pool counterparty
Complementary to Confidential RFQ
Confidential RFQ is a confidential swap venue. Noctis is a desk on top of Uniswap depth: encrypted vault accounting and intents, same Zama FHE stack, different job.
| Confidential RFQ | Noctis | |
|---|---|---|
| Job | Confidential venue | Private AMM desk |
| Liquidity | RFQ makers | Uniswap V2 |
| FHE focus | Size & direction in venue | Balances + intents → AMM fill |

Where Noctis fits
Mempool tools and ZK shields solve adjacent problems. Noctis owns one square: FHE-encrypted balances and intents, settled on Uniswap.
| Approach | What it protects |
|---|---|
| Private RPCs (Protect) | The mempool moment. Balances and history stay public. |
| CoW Swap | Strong MEV design via solvers. No encrypted balances. |
| Railgun | ZK shielding. A different stack and trust model. |
| Noctis | FHE balances and intents, plus proxy identity, on top of Uniswap depth. |
